The tyres are still performing very well, in all conditions and situations. Just had MOT and no advisories for tyres. - Very well, we noticed the driving improvement straight away. They have performed well in the recent ice and snow we’ve had.

I have had no issues with the tyres, once 'worn in' they've felt good on the road. - Hard to put my finger on it but they feel a little spongy. Apart from that they seem to work well in hot and wet weather.

Just as good as they were new! Unbelievable road holding, and very low wear. As good as any top branded tyre. 5 **** - Excellent all-round, road holding, noise level and superb in the wet!
